Question

An advantage of using yeasts rather than bacteria as recipient cells for the recombinant DNA of eukaryotes is that yeasts can ______________.

• A. Produce restriction enzymes
• B. Excise introns from the RNA transcript
• C. Remove methyl groups
• D. Reproduce more rapidly

Answer 1

The correct option is B Excise introns from the RNA transcript

Yeasts have been extensively used for functional expression of eukaryotic genes because they offer several advantages. Yeasts are the simplest eukaryotic organisms and like bacteria are single-celled, genetically well-characterised, easy to grow and manipulate. Since yeast is a eukaryote, it have an intron excision mechanism. Thus, it can be used for producing and expressing recombinant DNA of eukaryotes.
